The setup wouldn't even let me get pass the login screen

Eno could be so much better, like the Citibank version. It should let you set a credit limit and an expiration date to give you much better security functions. With long expiration dates, the potential for abuse is much greater.

I works really well for me. The unique card number for each site is a great security layer. Awesome!

Update Jan. 2026:
The extension works so infrequently that I can't believe this is a product they still want users to install. Whatever is going on at Capital One, they've abandoned making this product stable and reliable, which is a real disappointment. I used to really enjoy using the virtual CCs for online transactions, but at this point I'm having to go to the CapOne website to manage and retrieve them.

This extension has been adding more and more RUM telemetry components, which access more and more random URLs behind the scenes, and the actual functionality of the app has been declining constantly. Every time I try to use the extension lately, I get the "Checking Session" message and it just constantly spins. And accessing the virtual card list from the website is such a pain that at this point they're useless.

For the past month or so, Eno will not generate the virtual card numbers I already have, forcing me to reenter my credit card numbers time and again.

Works great for me so far. Happy to use an Add on to save using my real credit card number on every site

Really appreciate ability to not expose my credit card number. They finally fixed sign in to use browser login so I don't have to copy/paste my random password from a password manager. Really recommend.
